Re: [css3-content] ::outside::outside vs ::outside(2)

::outside::outside is, I would say, not allowed, since only one 
pseudo-element
may appear in a selection, and this element should be at the end. If there's
no special rule for ::outside, it means ::outside::outside is not allowed.

Could a spec editor confirm that fact ?
